{# src/fledermap/web/templates/_detail_favourite_button.html
   Standalone recording-detail page's favourite toggle -- deliberately its own small
   fragment, not a re-render of `_recording_panel.html` (which is filter-qs-dependent and
   carries prev/next), so `toggle_favourite`'s `?panel=detail` branch can swap just this
   button via hx-target/hx-swap="outerHTML" instead of forking into a duplicate route. #}
